Harington brought his girlfriend to the Game of Thrones Season 7 premiere this week, and they couldn't stop beaming on the red carpet. She stunned in an Erdem frock while he looked dapper in his Dolce & Gabbana suit.
Leslie and Harington first started dating in 2012 after meeting on Game of Thrones. "If you’re already attracted to someone, and then they play your love interest in the show, [it] becomes very easy to fall in love," Harington said last year.
Harington and Leslie were on and off for a few years. But while Leslie's character has been killed off the show, her romance with Harington is very much alive and well.
"I think that's the really special thing about it is that we met on this show and here we are seven years down the line back here promoting Season 7," Harington told ET at the premiere. "I mean it's mad. It's such a special thing. I'm so privileged."
Harington and Leslie have even managed to make things work despite their different schedules. "I’m very proud of him," Leslie told The Telegraph last year. "There’s an understanding that comes with the job, an understanding of being busy and when you have to say 'Sorry, I’m just going to bugger off for two months to film.'"
And the couple has been spending more time together in recent months. Earlier this year, they attended the 2017 Olivier Awards and went on a romantic trip to Greece. Harington even told Esquire that he and Leslie were moving in together.
"It's as much her relationship as it is mine and I can't speak for both of us," he added. "But yeah, we are very, very happy. So that's what I'll say about that."
Harington has tried to keep his relationship with Leslie as private as possible. So it's unclear if they are thinking about an engagement. But many GoT fans are hoping that Harington will eventually propose.
